A pilot flies an airplane in a vertical circular loop at a constant speed õ = 160 m/s. If the pilot’s apparent weight at the top of the loop is one-third of his true weight when he is on the ground, find the radius R of the plane’s circular path. answer is 1960 m but i need ...

An airplane's velocity with respect to the air is 580 miles per hour, and its bearing is 332 degrees. The wind, at the altitude of the plane, is from the SW and has a velocity of 60 mph. What is the true direction of the plane, and what is the speed with respect to the ground?
